Unintended consequences of eliminating Medicare payments for consultations e-methods. Study population inclusion criteria Our study population was drawn from the Thomson Reuters MarketScan Medicare Supplemental claims database and included Medicare beneficiaries who had any of the ICD-9 diagnoses listed in (1) or had any claim for a prescription medication belonging to a class of drugs listed in (2). Given our non-randomly drawn sample of Medicare beneficiaries, we adjust all analyses using the Centers for Medicare and Medicaid Services Hierarchical Condition Category (CMS-HCC) risk-adjustment system (version 2010), which uses nationally-representative coefficients derived using age, sex, and clinical diagnoses. The CMS- HCC score is used in risk adjustment of payments for Medicare Advantage plans. For all analyses, we also included sensitivity analyses in which the risk scores are omitted (e-table 4). 1. Any individual who have an International Classification of Diseases, 9th edition (ICD-9) diagnosis of ANY of the following: (401-405) hypertensive diseases (410-414) ischemic heart disease (415-417) pulmonary heart diseases (420-429) heart failure and related diseases (430-438) cerebrovascular diseases (440-448) vascular diseases (451-459) other vascular diseases (249-250) diabetes mellitus OR 2. Any individual who had a claim for ANY of the following prescription medications: HMG-CoA reductase inhibitors (statins) Other lipid-lowering agents Diuretics ACE inhibitors Angiotensin II receptor blockers (ARBs) Vasodilators Beta-blockers Antiarrhythmics Cardiac glycosides

On the right hand side are 2010 fees for office visits, which physicians were instructed to substitute towards. The % change column describes the change in fees for 2010 office visits compared to 2009 fees for consultations. Codes 99201-99205 are office visits for new patients. Codes 99211-99215 are office visits for established patients. All fees are national Payment Amounts for outpatient professional fees derived from the Medicare Part B Physician Fee Schedule.

e-table 4. Sensitivity analyses The following table lists interrupted time series estimates of the 2010 Medicare policy s effect on spending and volume, by type of patient encounter as well as for all encounters. The base model results (row 1) are compared to results from sensitivity analyses (rows 2-6). Sensitivity analyses are alterations from the base model. P values are in parentheses.
